The length and width of a rectangle are 7 cm and (x-8) cm respectively. find the value of x if the area with of the rectangle is 42 cm squared.

to find the area of a rectangle is LxW=A

plug in the given numbers you have

L = 7

W = x-8

A = 42

7 * x-8 = 42

7x-56= 42

solve for X

answer: the area of the parallelogram below is 42 square meters.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
